Explicação passo a passo:

$\mathsf{d_{AB} = \sqrt{(x_B - x_A)^2 + (y_B - y_A)^2}}$

$\mathsf{d_{AB} = \sqrt{(4 - 4)^2 + (7 - (-8))^2}}$

$\mathsf{d_{AB} = \sqrt{(4 - 4)^2 + (7 + 8)^2}}$

$\mathsf{d_{AB} = \sqrt{(0)^2 + (15)^2}}$

$\mathsf{d_{AB} = \sqrt{0 + 225}}$

$\mathsf{d_{AB} = \sqrt{225}}$

$\boxed{\boxed{\mathsf{d_{AB} = 15}}}$
